This paper describes the development of a new generation of power converter, used to power telecommunications equipment. A telecommunications converter must comply with the psophometric noise standard CCIF-1951 and the IEC1000-3-2 harmonic standard. While the IEC1000-3-2 standard is easily met with active power factor correction techniques, a high degree of effort is usually required to meet with the psophometric standard. Therefore, a control methodology utilising a three-phase phase-locked loop is introduced as a method of complying with the psophometric standard under distorted mains conditions. Simulations show that combining this with a novel feedback controller, results in an improved load step response over using a traditional proportional integral type controller
